To all wlw/n 'it may concern:

Be it known that l, Geenen A. Sinn, ctizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a speci- :tication My present invention relates to tabulating mechanism. for typewriting machines, and its principal object is to provide new and improved reversible tabulating mechanism which is adapted to select columns during movements of the carriage in both directions. More specifically, the object of my present invention is to improve the construction disclosed in my prior Patent No. 1,132,286, granted March 16, 1915.

To lthe above and other ends which will hereinafter appear, my invention consists in the features of construction,combinations of devices, and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings which illustrate the preferred form of my invention applied to a No. 10 Remington typewriting machine,

Figure 1 is a fragmentary front to rear vertical sectional view of said machine.

Fig. 2 is a plan view of a set of my improved column selecting stops.

Fig. 3 is a fragmentary rear elevation, partly in section, of my improved tabulating mechanism. A

Fig. i is a fragmentary horizontal sectional view, taken on a plane indicated by the dotted line .fc-m in Fig. 3.

Fig. 5 is a view corresponding to Fig. 4l.

`butshowing some of the parts in different Vto the main frame of the machine.

Referring first to Fig. 1, the main frame of the machine is shown as comprising a base 1, posts 2 and ay top plate 3, above which are fixed trackways, onl'l the rear one, 4, however, being shown.

aid trackways codiagrammatieally shown herein. operative with the front face of the platen are type bars, not shown, of the usual Remington construction. A releasable feed rack 8 is carried by arms 9 fulc'rumed at 10 on ears l1 fixed to the rear part of the carriage. Said feed rack normally meshes with a feed pinion 12 that is operatively connected with escapemcnt wheels 13, said wheels coperating with a feed dog 14 mounted on a rocker 15 that is operative in the usual way by the printing key levers.

The tabulating mechanism comprises a stop bar 1G Inounted on angular arms 17 se. cured to the rear part of the carriage and extending rearward therefrom. Said stop bar is toothed on its upper and lower faces to provide notches a letter space distance apart, which notches are` adapted to receive a plurality of adjustable column stops 18,` there being five such stops in the present instance, as shown in Figs. 1 and 3. These column stops are generally similar in con* struction, being notched to straddle or fit over the stop bar from the rear but differ from each other in that each is provided with a rearward projection, lug or stop proper, these projections being at different heights for the different stops. Thus the stop lug 18a of the leftihand column' stop 18 of the series (considered from the front of the machine) is at the top of said column stop, while the stop lug 18 of the right-hand stop of the series 'is at the lower end of said stop, and the stop lugs '18, 18c and 1Sd of the intermediate column stops are in horizontal planes between the lugs 18a and 1S, these planes being successively lower than the plane of the upper stop lug. In other words, the stop lugs are arranged in a series of steps at progressively Varying heights.

Cooperative with the column stops are a set of tive frame stops, one for each column stop. The chief features of my present in vention reside iu the construction, mounting y and control of these'frame stops.'y Said frame stops are in the form of plates o1' slides shaped as best shown in Fig. 2, wherein the plates are numbered respectively 19, 20, 2], 22 and thevstop plate 19 being the topmost one of the set, t-hc stop plate 23 being the bottom slop, and the other three being successive intermediate stops. Grenouslot.y 34 atthe left jandfa narrower slot 35 'ati erally, these stops or plates are similar in construction, each comprising a notch 24 in its frontfacethat is adapted tocoperate with its associate stop lug on the collunn stop. From this notch the front edges 25 incline rearward, to equal extents providing two cam faces. At its4 sides each stop platel is provided withl laterally projecting lugs 2G, there being a pair of suchlugs at` each side, one at the front and one at'the rear,r the side 27 betweeneach pair having a plagnev face.. Also each stopV plateV is providedwvith a s101328 which. is adapted for cooperationlwith any. actuating lever .hereinafter 'described.v These slots arefldiiferently locatedor.; each stop'iuas willbe understood.

The middle stopy plate 21.

The stop plates are mounted one above the other in the head or top portion of a verticali frame 37 arranged at the rear. of'` the main; frame andi detachably secured thereto. Near its top the frame 37 is pro vided with lugs or thickened portions 38 that it into a depression in the rear of the top` plate Band between lugs 3a depending;

from the sides of said depression (Fig. 3). Screws 39 passing sidewise through the lugs 3 and into the thickened portions 38, secure the frame-37 to the top plate. These, screws are headless. The -constructionis suchkthat unnecessary strain on the lugs 3a iseliminated and the liability of the lugs to break off` under a suddenjarringsuch as sometimesoccursin shipping the machines, is

minimized. Near the lower end ofthe frame- '37 other. devices are provided for attaching it'. tothe base 1. The'lower attaching devices. comprise exteriorly threaded bushings 40, which are threaded into tappedfholes formed in thickened portions 37a of theV frame 37'l (see especially` Figi. 8). These bushings .arenprovided .with nicks so thatv they maybe readily. adjusted by, means of a suitableztool. The rear face ofv the base` 1 is not machined, nor is `the front ,faceof theV lower, portion of the frame. 37, and if these parts wereV brought into Vdirect contact it would Inotbe possible in' practice toobtainvan even or. close engagement of the trame, 37..w1th.the frame kor base 1, butY on f thecontrary in nearly all .A casesthe, frame twouldrvbe skewed, The. screw bushings 10:` provideVV adjustable abutments which` mayv be ,turnedi in.. through the frame 847. indes pendently of each other untilv proper: conl tact with the base ,lis obtained.. The bus-hings 40zare drilledi and countersunk to receive headed screws 40u', these screws passing loosely through, the .bushingsl and. being threaded into tapped holes inthebase 1,

thus firmly securing thelower portion of.

the frame 37 to said base. It willbeunderstood that the screwsarenot, secured in Vplace until;y after the bushings' 40 have been adjusted. The frame 37 is generally U-shaped in cross-sectiombeingopen atits front side. Its topnor upper portion is somewhat thickened (Fig. 3) and it spreads bothlaterally and.` forwardly, providing a, sort. Vof head portiondl thetop ofiY which ismachined so that its face is in a horizontal pjlaneandv slightly below` the bottoms of the; column stops 18fwhichare forward of the front portion of said head 41. At each side of. the head is arranged apair otvertical, posts a2 disposed. one in front otthe other,V these posts being yscrewed down into the top of the head and providingsupports for sets of roller bearings.

These bearings are in the*` form of flanged disks or rollers 43, the` lianges 44E beinglbelow the body portions or bearing,` portionsA proper of the disks. The` disks or rollers arc stimply strung on the posts and bear on each other, the bottom one supporting all et the others. There are live disks or roller bearings on each post. In other words there 4are tive sets of bearings, each set comprising four bearings in the same horizontal plane which `four coperate to guide and support one of the slides or stop plates 19H22 This will be clearly understood from an inspection of Figs. l and 8. The bottom slide 23 is supported on the flanges of the bottom set of disks 4.3, and its i'iarallel side edges 27 cooperate with the body portions of the bottom disks during to-and-fro sliding movements of said stop plate 23, these sliding movements being limited by the lugs 26 which act as stops in cooperation with the associate disks or roller bearings 43. Similarly the other stop plates of the set are guided and supported by their associate roller bearings, each stop plate being confined between the flanges of its own bearings and the flanges of the bearings next above, these flanges preventing displacement of the stop plates vertically. Also the flanges serve as separators, holding each stop plate in the pile separated from its fellows, the friction in operation being consequently much less than if the faces of the plates contacted'with andrubbed on each other. On the tops of the top set of bearings 43 is arranged a set o'f plain disks 45. A cover7 hood or housing 46 is arranged over the whole set of stop plates and extends downward over the sides of the rear head 4l, this cover being secured in place by nuts 47 which are screwed on the upper reduced threaded ends of the posts 42. The front side of the hood 46 is open so as to permit the stop plates to be slid or projected forward rectilinearly for coperation with the lugs on theirassociate column stops. The stop plates are so arranged that the top plate/19 is in the same horizontal plane as the top lng 18a. while the underlying plates 20, 2l, 22 and 23 are respectively in the planes of the stop lugs 18h, 18, 18d, 18", the result being that when the stopplates are selectively projected their notches 24 will coperate'with the stop lugs ot' associate column stops only; `intervening column stops being skipped or passed. The individual, independent guides or bearing devices or disks 43 promote easy and accurate operation ot the stop plates. l

For selectively actuating the stop plates, trains ot' key controlled devices are provided. each train comprising an upright lever ineinber 4S, the set of lever members heilig' arranged side by side and pivoted on a rod 49 supported by ears 37b projecting Jforward troni the middle portion of the sides ot' the .frame 37, which frame houses the set. One

, endet' the rod 49 is reduced and threaded and the other end is provided with a nick The upper end portion ot each actuating lever 48 is curved li'ori'ard and upward, cach lever cooperating with one ot' the notches. 28 and passing vlrcely through slots in thc` other stop plates. This will be, plain from an inspection ol VFigs. l and 3. Thus the lett-hand lever 4S (which is the right-hand one ot' the set when viewed from the rear as in Fig. 3) passes 'freely up through the slots 36, 34, 32 and 30, and operatively engages with the slot 28 in the top stop plate lf). Similarly the next lever 48 passes it'reely upward through the slots 236, 3L and B2, engaging in the slot 2S in the stop plate 20; and so on with the other leversI 48, the right-hand lever 4S engaging operatively in the slot 29 of the lowernu'ist stop plate 23 and passing freely upward through the slots 33, 8l and 29. This construction providesl lor intercliangeability otI the leverslS, all the members et the set being alike in forni. Back ot' their pivots the levers 14S are notched, as indicated at 50, for coperaties with restoring springs 5'1, which artl housed in the frame 37. Said springs are seated in holes indicated at 5la which holes are drilled at an inclination upward and rearward through the enlargen'ient 37 (Figs. l and 7), the axes of these holes coinciding with planes passing through the middle ol the kert's 37. lt may be noted that as a mattei' oi. construction the holes are drilled before the kerts are cut. The springs 5l are confined between the closed upper ends of the holes 51.EL and laees ot' the notches 50. By reason of this construction it is unnecessary to hook or secure the end portions ol the springs to anchor them or attach them to the parts on which they act. At their lower ends the levers 4S pass through parallel guide slots or kert's indicated at 237, cut in a :forwardly projecting rib 57f on the l'raine. 37. The lower end portions 4S of the upright levers project horizontally -l'orward tlnfough a rectangular opening indicated at l that is cut in the rear olE the hase l. The ends 4S are pivotally connected at 52 with jt'orwardly extending horizontally disposed links There are live of these pivotal points 52 and they all lie in the saine trans verse horizontal straight line or axis as will be clearly understood by reference to Fig. 3. The forward ends ol the links 53 are pivotally connected at 54 with angular levers 55 mounted on a stationary pivot rod 5G and the pivot rod 56. The cross bar of the bail is arranged behind. therlevers andis operated by them. Near its opposite end said cross bar is Connected byV parallel rearwardly extend-ing links 64 (Fig. 6) with crank arms fixed to andextending dowin ward from the end portions of a rock shaft 66, said rock shaft being provided with projections 66aN that bear in stationary brackets 67. The connection betweenY thelinks 64 andthe arms 65 permits of ready detachment of the links. The lower ends of the arms 65 are formed with key-hole slots 65aN which are engaged by headed pins 64 proj ecting laterally outward from the links'y 64.y The heads of these pins are cut oif at. the top and bottom sides so that theheads are of oblong shape, permitting fthem. when vertical to pass throughy the key-hole slotsY 65a. This is done before connecting the forward ends of the links A64v and while holding saidV links vertical. After being thus inserted the'links are swung forward and the pins 64".L drop to the bottoms or narrow ends of the slots 65a through which the heads of the pins 641L cannot now pass. Flat locking springs 65h,` secured to the outer faces of the arms 65, normally prevent theV pins .64a from rising .in the slots 65a. By

pulling the lower free ends of the lockingf springs 65b outward away from the faces ofthe arms 65 the pins 64 are-freed so that the links 64 ymay be disconnected. The

right-hand larm 65 isv provided near its lower end with a forward extension 65c to which is pivotally connected the lower end of an angular link 68, the upper end of said link being connected with a lever frame 69 pivoted at 69a on a stationary bracket 69b (Fig. l). both a retarding device 69c 'and also a rc` leasing pinion 70. Said pinion underlies the feed rack 8 and is adaptedV when one fof theitabulating or columnselecting. keys 59 is operated to swing said releasing pinion 7 0 upward to releaseL said feed rackfrom lrengagement with-the feed pinion 12. More specifically, when a key 59 isV actuated its associate lever 55 `will operate to swing. rearward-.the bail 63, the movementof the bail being transmitted bythe parallellinks 64 "to thecrank-arms androckshaft 66 and Said lever framesupportsf through the extension 65c and link 68 to the lever frame 69 and pinion 70. The construction provides ythat motion will be transmitted'to the link 68 aswell when the lefthand one of the set of keys 59 is actuated as when the left-hand one ofthe set of keys 59 is actuated as when the right-hand'one of said keys is actuated, although the right.- hand key is more nearly in a direct line forward of said. extension 65C thanis the left-hand key 59, which left-hand key is considerably at one side.

It will be apparent that when one of the keys 59 is depressed, its movement will be transmitted through the train of devices comprising the associate lever 55, link 53 and lever 48 to theconnected slide or `frame stop whichy will be projected or slid forwardinto the path of the associate column stop lug so as to coperate with the latter to arrest the carriage followingA its release.V The forward proj ection` of the selectedv frame stop or slide will not aect` any of the other framev stops,. as has been eX'-` plained; and itwill. also be apparent that ifthereby any column stop or stops to theV right of the projected frame stopl and inv advance of thecolumn stop that is inthe same horizontal plane-with said projectedI stop, suchfadvance column` stops will be skipped or passed. Also itfislplain that this applies whetherrthe movement of the carriage is from right. to left as is usual in tabulating, `or Vfrom left to 'right inreverse direction. Assumingthe movement is from right to left it willbe `understood that the carriage will,.whenreleased, move freely tothe left untilf the stop lug. of the selected column stop, say,.for example, the lug` 18% contacts with the left-hand cam face 25 of the proj ected slide 23, which it willido some distance to thev left of the notch 24;` As the. motion ofthe carriage, continuesy thefstop plate 23 will be cammed or forced slightly`y backward against the pressure eXerted'upon the` depressedfkey 59, there being enough resiliency in the parts between said key and the stop plate to permit .such backward camming yoff said stop plate without appre.- ciably affecting the key. As soon'as the stop lug 18 enters the notch 24 the st op plate 23 will snap forward until arrested by the contact of thestopy lugs 26-with the bearings 48. Thepartsat this time willlbe in the position illustrated in Fig. 5.

The stop lug .18e is embraced between the walls ofthe engaging or lockingnotch 24,. and the left-hand face. of the stop lug is in contact with the left-hand face or7 wall of said notch, which face or wall acts as an arresting device. If'the key 59 be now released the parts controlled by it will returnv to normal position, the single restoring.j spring 5l being effective duringsuch returnv movement both on the lever 4&5v and the slid able stop plate 23 positively operated thereby. A similar operation ot' the parts will take place at each subsequent coluum selecting operation durin the run oit the carriage from right to le t. W'ith the carriage at or near the lett-hand side, if it be desired to arrest it at any desired column during the return moven'ient, the operator as before impresses the selected key 59, projecting the associate sl idable stop and releasing the carriage. The carriage, however, is restrained from moving toward the leit by the disengaged hand ot' the operator who pushes the carriage against the pull of the motor back toward the right. This brings the stop lug ot the selected column stop into engagement with the left-hand cam 't'aee 25 of the projected slidable stop, said lug cooperating with said face to cam or force the slidable stop rearward until the stop lug comes opposite the notch Qt. whereupon the slidable stop will snap forward and the notch will embrace the sides ot the stop lug as in Fig. 5, the right-hand wall ot' the notch acting as au arresting device. The key 5S) is thereupon released. The timing is such that beilore the locking notch Q-t frees the column stop lug the feed rack S will have engaged with the 't'eed pinion 1Q, thus restoring the carriage to the control ot' the eseapement devices. rlherealter the entry in the column is written as in ordinary right to lelt tabulating or column selecting. rlhe above described operation may be repeated each time it is desired to etl'ect a reverse tabulating or column selecting. As is well understood, reverse tabulating or column selecting may be conveniently employed in listing work or the like.

It will be observed that my present invention is an improvement on my prior construction in that the column selecting stops slide into and out ot forward or operative position instead of rotating about the axis of a fulcrum pin. The present construction gives more nearly direct control of the projected stop by the finger key, reducing to a minimum the shock 't'elt by the finger of the operator when the carriage stop strikes the projected stop. The slidalole stops are positively connected with and controlled lov their actuating levers in both forward and rearward movements, thus dispensing with a return spring for the slidable stop necessary with the former construction. Uniformity ot operation is also promoted, the operation of the slidable stops being substantially the same both for ordinary tabulating and for reverse tabulating.

The tabulator supporting frame 37 has advantages over prior constructions. By reason of the pivotal mounting of said frame on the screws 39 as well as of the adjustability of the screw bushings 4:0 the frame may he adjusted or swung on the screws 39 as pivots so as to bring the set 0f trame stopsx l) to 28 in proper relationship to the column stops. Thus before the screws #.'te are threaded into place it will be understood that by screwing in slightly on the bushings l0, after they have been brought into contact with the rear face ot the base l at the sides ot the opening l, the frame 3T at its lower portion will move rearward correspondingly away from the tace of the base, and the upper end ot the frame 37 will be swung correspondingly forward about the centers 39, bringing` the Jframe stops that much closer to the path of movelncnt ot' the column stops. Similarly by unthreading the bushings fl() slightly and then pressing the lower end of the frame 37 forward until contact is made with the frame or base l, the trame stops will be swung correspomlingly rearward away from the path ot' the column stops. After this adjustment the trame 37 is fixed by screwing in the screws 410% As a result of this construction nice adjustmentot the relationship between the trame stops and their associate column stops is provided for. Furthermore, the construction and mounting of the tabulator Jframe 37 provides for its ready displacement when ever it is desired to get at the back of the machine, as for adjusting the cscapemeut devices, and such displacement is had without disconnecting the levers -lS :trom their links All that it is necessary to do is to unscrew the screws 3S) and the screws -lA f after which the 'trame 37 may be laid or swung back to a nearly horizontal position it desired, the swinging taking place about the line containing the pivotal points as an axis. The dotted lilies in Fig. 1 indicate the frame in a. swung-back position and make it plain that the rear portion ot' the machine is at such time entirely exposed. To accomplish this result in prior constructions itwas necessary to disconnect the lower ends of the tabulator levers from the trains of devices connecting them with the tabulator keys, this requirine a number o't' operations corresponding wit i the number ot' tabulator levers in the set. Such disconnections are avoided by the present construction.

Various changes may be made without departing from my invention.,V
